https://bugzilla.kernel.org/show_bug.cgi?id=201685 --- Comment #199 from Ortwin Glück (odi@xxxxxx) --- (In reply to Rainer Fiebig from comment #195) > My VirtualBox-VM seems immune to this issue. Perhaps VMs have just the right > "hardware". Yeah, I've been wondering. Qemu only exposes single-queue devices (virtio_blk) so bugs in MQ can not trigger here I guess. Also "hardware" timing is much different in VMs so race conditions may not trigger with the same frequency. Also CPU assignment/scheduling may be different with respect to barriers, so memory safety problems (RCU bugs, missing barriers) may behave differently. I had no luck with vastly overcommitting vCPUs either. -- You are receiving this mail because: You are watching the assignee of the bug.
